baffinSediment core spanning 200,000 years from Baffin Island shows how ecologically distinct the last century has been.

An international team of scientists including Biology professor John Smol, research scientist Neal Michelutti, and M.Sc. student Cheryl Wilson are part of an international research team whose analysis of sediment core from a remote Arctic lake on Baffin Island provides compelling evidence of unprecedented environmental changes occurring over the past few decades wrought by human activities. The sediment core predates by about 80,000 years the oldest cores from the Greenland Ice Sheet, capturing two ice ages as well as three interglacial periods.
